retaining ring and o-ring that need to be cleaned every 100
hours or once a year (whichever occurs first).

2. Remove sediment cup (A) from fuel valve. Remove
o-ring (B), retaining ring (C) and screen (D) from fuel
valve.
3. Wash sediment cup, o-ring, retaining ring, and screen
in a nonflammable solvent. Dry them thoroughly.
4. Place screen, retaining ring, and o-ring into fuel valve.
Install sediment cup and tighten securely.

Oil
Oil Recommendations
We recommend the use of Briggs & Stratton Warranty
Certified oils for best performance. Other high-quality
detergent oils are acceptable if classified for service SF, SG,
SH, SJ or higher. DO NOT use special additives.
Outdoor temperatures determine the proper oil viscosity for
the engine. Use the chart to select the best viscosity for the
outdoor temperature range expected.
* Below 40°F (4°C) the use of SAE 30 will result in hard starting.
** Above 80°F (27°C) the use of 10W30 may cause increased oil
consumption. Check oil level more frequently.
NOTE: Synthetic oil meeting ILSAC GF-2, API
certification mark and API service symbol with “SJ/CF
ENERGY CONSERVING” or higher, is an acceptable
oil at all temperatures. Use of synthetic oil does not
alter required oil change intervals.
Checking Oil Level
Oil level should be checked prior to each use or at least
every 8 hours of operation. Keep oil level maintained.
1. Make sure generator is on a level surface.
2. Clean area around oil fill and remove oil fill cap.
3. Verify oil is at the point of overflowing at oil fill
opening.
4. Replace and tighten oil fill cap.
Adding Engine Oil
1. Make sure generator is on a level surface.
2. Check oil level as described in Checking Oil Level.
3. If needed, slowly pour oil into oil fill opening to the
point of overflowing at oil fill.
4. Replace and tighten oil fill cap.
